Budget Development Process

Phase 1: Preliminary Estimate

Early planning requires rough order of magnitude estimate:

  • Based on similar projects
  • Per-square-foot comparisons
  • Feasibility analysis

Purpose: Determine if project is financially viable.

Phase 2: Schematic Design Budget

Once design direction set:

  • Detailed cost estimate for preliminary design
  • Breakdown by system and component
  • Identification of major cost drivers

Purpose: Validate design approach; adjust if needed.

Phase 3: Design Development Budget

As design becomes more specific:

  • Detailed quantity takeoffs
  • Specific material and equipment pricing
  • Labor rate estimates
  • More accurate contingency

Purpose: Refine estimate for budget lock.

Phase 4: Construction Document Budget

Final estimate before construction:

  • Complete specifications and materials
  • Quantity and specification-based pricing
  • Detailed labor estimates
  • Bid solicitation from contractors

Purpose: Establish construction budget.

Phase 5: Cost Control During Construction

Ongoing cost management:

  • Change order tracking
  • Value engineering for cost savings
  • Procurement optimization
  • Schedule efficiency monitoring

Purpose: Keep project on budget.

Contingency Planning

Why Contingency is Necessary

Construction always involves unknowns:

  • Hidden conditions discovered during excavation
  • Design changes requested during construction
  • Weather delays
  • Material availability issues
  • Labor challenges
  • Code interpretation questions

Appropriate Contingency

Early Project (Feasibility): 20-30% contingency

  • Significant unknowns
  • Rough estimates
  • High uncertainty

Design Phase: 10-15% contingency

  • Design becoming more detailed
  • Estimates more accurate
  • Some unknowns remain

Bid Phase: 5-10% contingency

  • Design complete
  • Contractor pricing basis
  • Risk lower but not eliminated

Construction: 3-5% contingency

  • Limited unknowns remaining
  • Use for genuine surprises
  • Careful contingency management

Contingency Management

Protect contingency:

  • Use for genuine unknowns only
  • Don’t use for design changes
  • Don’t use for poor planning
  • Keep contingency reserve separate

Value Engineering

Reducing cost without compromising quality:

Material Substitution

  • Choose materials meeting codes at lower cost
  • Local materials instead of imported
  • Durable basic materials instead of premium finishes

Simplification

  • Simplify designs reducing complexity
  • Standard components instead of custom
  • Reduced site complexity

Sequence Optimization

  • Efficient construction scheduling
  • Reduced inefficiencies
  • Minimized weather exposure

Scope Modification

  • Reduce scope to essentials
  • Phase project over time
  • Defer non-essential features

Value engineering should enhance value, not reduce quality.
